Interesting solution and thread. I have gotten mixed reviews from folks on the other end of calls..."sounds clear as a bell" .."or "sounds pretty noisy" I never made the connection of wind at higher speeds possibly being the factor but will keep that in mind going forward and look to do this smart mod if needed.

I have to say I would be pretty hesitant to replace the mic because of the SYNC voice recognition stuff. I'm sure Ford did a lot of tuning on the system using the included mic. Even if it made cell calls better, it could potentially really found up voice command recognition. No idea for sure, I just would be concerned about this aspect before replacing the mic.
